Description
When running the complete "all" profile in piglit against mesa's swr driver, ext_transform_feedback-immediate-reuse-uniform-buffer most of the time fails, but not always.
It seems its pass rate is ~5%.
AFAIK, this is not new for 17.2.x not a recent regression.
A typical piglit report is as follows, although varies from failed run to run:
Detail | Value ------------+--------------- Returncode | 1 ------------+--------------- Time | 0:00:00.211612 ------------+--------------- Stdout | Probe color at (224,0) | Expected: 223 31 223 | Observed: 0 0 0 | Probe color at (240,0) | Expected: 239 15 239 | Observed: 0 0 0 ------------+--------------- Stderr | WR detected AVX2 | vert shader 0x7f492c287000 | frag shader 0x7f492c285000 | so shader 0x7f492c283000 | fetch shader 0x7f492c281000 | fetch shader 0x7f492c27f000 | SWR destroy screen! ------------+--------------- Environment | PIGLIT_PLATFORM="mixed_glx_egl" PIGLIT_SOURCE_DIR="/home/local/piglit" ------------+--------------- Command | /home/local/piglit/bin/ext_transform_feedback-immediate-reuse-uniform-buffer -auto -fbo ------------+--------------- dmesg |
Environment is an Ubuntu Xenial with custom LLVM packages installed and locally compiled mesa and mesa dependencies. If needed, I can provide a docker image with which to test.
